SPECIFICATION forming part of Letters Patent No. 532,757, dated January22, 1895.

Application filed November 11, 1893. Serial No. 490,708. (No model.)

To all whom it may concern.-

Be it known that I, LEO F. BER'HEIDE, a citizen of the United States,residing at Richmond, in the county of Wayne and State of Indiana, haveinvented certain new and useful Improvements in Feed-Cutters; and I dohereby declare the following to be a full, clear,

' and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same. Thisinvention has relation to that class of feed cutters in which the feedto be cut is I ment and combination of the several parts substantiallyas hereinafter described and particularly pointed out in the subjoinedclaims.

In the drawings Figure 1 is a side elevation of my machine showing oneside of the same and the position of gearing. Fig. 2 is a side elevationof the opposite side of the machine showing the gearing on that side.Fig. 3 isa longitudinal vertical section. Fig. 4 is a top plan View.Fig. 5 is an inverted plan View of a section of the under surface of thestructure. Fig. 6 is an end elevation of the body of the machine, thefriction pulley, and the framing to which it is attached.

In Fig. 4. I I represent the side sills of the box frame of the machine.

P is the main shaft uponthe end of which is mounted the driving pulley Oand a pinion R which inesh'esint'o a spur wheel R. mounted on a shortshaft 7 upon. the/ outer end of which is fixed a pinion 0 Fig. 1,arranged to mesh. into the cogs on the inner surface of the rim of thewheel B, Fig. l, which in its turn operates the lower feed roll by meansof the pinion C, Fig. 2. This pinion O meshes into the cogs on the innersurface of the rim of the wheel B, Fig. 2, which is provided on itsperiphery with the spur gear and operates the pinion (l on the shaft ofthe upper feed roller.

A skeleton frame or spider K, Fig. 3, is mounted on the main shaft P induplicate and constitutes the heads of a cylinder to which the knives ii't't' are bolted and on which they revolve.

L is-the cutter bar and'forms thecounter edge in connection with whichthe knives t' t' it perform the operation of cutting and is bolted to abracket cast on to the side of the frame. a

The framing, the cutting mechanism, the. feed rollers, the train ofgearing for transmitting motion to the feed rollers andcuttingmechanism, and the means for throwing the parts .intoa nd out of gearshown in the accompanying drawings may be of the usual and well knownconstruction, or of any suitable construction, and for this reason afurther description thereof is not required for aproper understanding ofthe presentinvention which relates solely to the means for directing thefeed positively between the rollers and to the means co-operatingtherewith for holding the upper roller into positive engagement with theupper surface of the feed and for permitting it to rise and fall toadapt it to inequalities in the bulk of the feed passing between therollers.

G, Fig. 1, designates an arm or bar, of which two of similarconstruction are used, one being placed on each side of the frame infront of the feed rollers and on the outside of the box. These arms eachextend from a point just below the box to a place on a plane with thejournals of the upper roller, A, which j ournals are received withinslots formed in brackets, a, so as to permit said roller to rise andfall for the purpose hereinabove stated.

The upper ends of the arms, G, are curved,

as shown at G, and embrace the journals of said upper roller, and saidarms are also provided with branches, G which are-curved in a directionopposite to those just referred to and terminate in eyes which embracetheends of a rod,8, that extends across the frame and moves bodily,within the opening 9, with the upper feed roller.

, M designates a gate the rear end of which is'located adjacent to saidupper feed roller and is hinged to said rod, 8, and M designates a plate(which may be stationary) the rear end of which is located adjacent tothe lower feed roller A, said gate and plate together forming a throatvthrough which the feed to be cut is fed between the rollers.

As the substance to be cut is passed in between the feed rollers thevolume of the same operates to raise the upper feed roller and thelarger the bulk the more the roller is raised until checked by the frameor bracket in which the journal moves. As the upper feed roller israised by this means it carries with it the curved arms G and G thelatter carrying the rod 8 to which the lower edge of the gate M ishinged, thus increasing the space under the gate just as the space isincreased between the rollers.

The gate M is rectangular in form and has a smooth lower surface and isarranged at an angle so that the front or upper end is higher than therear or lower edge. This angle or pitch serves to give direction to theloose or crooked stalks or fibers of the substance to be cut andprevents the same from being deflected from the opening or throatbetween the rollers thus insurin g a perfect and positive feed to therollers of any and all substances passing into the box.

In order to hold the upper roller, A, yieldingly but positively intoengagement with the upper surface of the grain being fed, I employ aframe N and an arm g. Said frame is attached to vibratory arms e thatare pivoted to the box, and it is preferably provided with a frictionroller 71. and has a suitable attachment with the arms G, and said arm 9is pivoted at one end so as to move with the arms G and frame N and hasa counterbalancing weight (1 at its free end. As the bar G is raised bythe upper feed roller the vibrating arm carrying the friction pulley israised carrying the curved arm g and the weight (I. It will be seen thatthe pressure of the upper feed roller upon the substance passing betweenthe rollers is regulated by the weight of the counterbalance d and alsothat the means which hold said upper roller into yielding contact withthe grain also serves to hold the inner edge of the gate M into thelowermost position which it should, for the time being, assume.

The mechanism shown in Fig. 9 is the means commonly employed forthrowing the knife cylinder and feed rolls out of gear, and the train ofgearing shown in Figs. 11 and 12 is common to most devices of thischaracter. Therefore they need not be more particularly described; but

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

1. In afeed cutter, the combination with the feed rollers, one of whichis movable toward and from the other, and a pivoted gate for directingthe feed to between the rollers, of a movable arm, connected with thejournal of said movable roller and also with an end of said pivotedgate, and a weight, acting upon said movable arm, substantially asdescribed and for the purposes specified.

2. In a feed cutter, the combination with the feed rollers, one of whichis movable toward and from the other, and a pivoted gate and a plate,forming a throat through which the grain is delivered to between therollers, of a movable arm, having one branch engaging the journal ofsaid movable roller and another branch connected to said gate,substantially as described, whereby the pivoted gate will be caused torise and fall and thereby increase or diminish the diameter of thethroat simultaneously with the rise and fall of said movable roller,substantially as specified.

3. In a feed cutter, the combination with the feed rollers, one of whichis movable toward and from the other, and a movable arm, connected withthe journal of said movable roller, of an arm, having a counterbalancingweight at one end and pivoted at its other end, said arm also havingconnection with said first mentioned movable arm, substantially asdescribed.

4. In a feed cutter, the combination with the feed rollers, one of whichis movable toward and from the other, and a movable arm connected withthe journal of said movable roller, of a pivoted frame, connected withsaid arm, and a weighted arm, engaging said frame, substantially asdescribed.

5. In a feed cutter, the combination with the feed rollers, one of whichis movable toward and from the other, and anarm connected with thejournal of said movable roller and raised and lowered therewith, of avibratory frame engaged with said movable arm, a roller supported bysaid frame, and a pivoted weighted arm engaged with said roller,substantially as shown and described.

6. In a feed cutter, the combination with the feed rollers, one of whichis movable toward and from the other, and arms connected with thejournals of said movable roller and raised and lowered therewith, of atransverse rod connected with and raised and lowered by said arms, aplate located adjacent to one of said rollers, and an incline gatelocated adjacent to the other roller an having its lower end pivoted tosaid rod, substantially as shown and described.

7. In a feed cutter, the combination with the feed rollers, one of whichis movable toward and from the other, and movable arms connected withthe journals of said movable roller and raised and lowered therewith, ofa transverse bodily-movable rod connected with and raised and lowered bysaid arms, a plate located adjacent to one of said rollers, an inclinedgate located adjacent to the other of said rollers and pivoted at itslower end to said transverse rod, and means engaging said movable armsand serving to hold said movable roller and gate into yielding contactwith the grain being fed.

In testimony whereof I affix my signature in presence of two witnesses.
